"As to there being only thirteen in the list, it probably arose from the
blunders and carelessness of transcribers. Epiphanius, in his First Book
against Heresies, assigns this
reason, that the name of Jeconiah had been twice put down, and unlearned
persons ventured to strike out the repetition of it as superfluous;
which, he tells us, ought not to have been done, because Jehoiakim, the
father of king Jehoiakim, had the name Jeconiah, in common with his son,
( <130317> 1 Chronicles 3:17; <122415> 2 Kings 24:15; <242720> Jeremiah
27:20;
28:4.) Robert Stephens quotes a Greek manuscript, in which the name of
Jehoiakim is introduced."
